IMPROVEMENT IN BARBERS" CHAIRS.

Spacification forming part of Letters Patent No. 165,498, dated July 13,1875 application filed October 30, 1874.

To all whom it may concern Be it known that I, JOHN OTT, ofIndianapolis, in the county of Marion and State of Indiana, haveinvented a new and useful Improvement in Barbers Chairs; and I do herebydeclare that the following is a specification of the same.

In the annexed drawings, which make a part of this specification, Figurel is a perspective view of the chair; and Fig. 2 is an elevation, partlyin sections.

The same letters are employed in both figures in the indication of thesame parts.

A is the frame of the chair, and B is the foot-rest, supported on thesliding frame 0,

back F is separate from the arms, and hinged to the chair frame byhinges G on each side. In order to sustain the back of the chair, a bar,H, of strength sufticient amply to sustain the weight of an occupant ofthe chair, is hinged to the frame and extended upward, so as to bearagainst the back at I, where metallic lugs confine it. A pawl, K,isattached to the lugs by a pivot, and its teeth are made to engageratchet-teeth in the back of the hinged bar H. The arm of the pawl hangsdown and keeps the teeth normally engaged with the ratchet-teeth of thebar, so that the weight of the occupant will rest on the back and besustained by the bar, thus relieving the hinges. To lower the back it isnecessary to raise the arm of the pawl and disengage the teeth, whichbecome re-engaged when the pawl is released. To raise the back it isonly necessary to lift it, as the pawl does not interfere with movementin that direction. The

head-rest is adjustable also, being in like manner held by pawl andratchet M.

I am aware that a support for the back of the chair attached to theseat-frame and confined by a latch has been employed. My invention isdistinguished from that in this, that I extend the hinged piece andcause it to support the chair-back near its upper end, where it isconfined by the pawl. By this means the leverage is diminished and thedanger of breaking, which might result in a most serious accident to theperson being operated upon, removed.

What I claim as my invention, and desire to secure by Letters Patent,is-

In combination with the frame and hinged back, the hinged support H,fastened by a joint to the frame, and bearing against the back, where itis confined by the ratchet and pawl K, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

- JOHN OTT.
